after many tries, they find they can not quit their jobs and go day trading
after manay tries, they find the market is full of betrals, teasing, tricking and manipulations, you never know why it stops its drop at some magic number and starts to bounce hard, or you never know why it stops its nice rally at some seemingly msterious number
after many tries, they find the market is unpredictable, not like textbooks'describations, high higher low higher uptrend move, or low lower high lower...there are lots of msterious move
after many tries, they find an very exciting news may create an exodus of nice rally, they just can not figure out, the news is so good why the market is out
after many tries, they find some market rallies without any stop, day in day out, doubled, tripled , even 10 folds, even 100 folds, and it is still climbing
after many tries, they find some market drops without any rest, day in and day out, even 99.9% value is lost, it is still edging down, they never know
